The chemical senses—smell and taste—allow animals to evaluate and distinguish valuable
food resources from dangerous substances in the environment. The central mechanisms by …

Olfaction is a vitally important sense for all animals. There are striking similarities between
species in the organization of the olfactory pathway, from the nature of the odorant receptor …

Oxytocin promotes social interactions and recognition of conspecifics that rely on olfaction in
most species. The circuit mechanisms through which oxytocin modifies olfactory processing …

Olfactory deficits are present in numerous neurodegenerative disorders and are
accompanied by pathology in related brain regions. In several of these disorders, olfactory …

Sensation is an active process involving the sampling and central processing of external
stimuli selectively in space and time. Olfaction in particular depends strongly on active …

Generation of neuronal diversity is a biological strategy widely used in the brain to process
complex information. The olfactory bulb is the first relay station of olfactory information in the …

Olfactory cortex pyramidal cells integrate sensory input from olfactory bulb mitral and tufted
(M/T) cells and project axons back to the bulb. However, the impact of cortical feedback …

Written by a neurobiologist and a psychologist, this volume presents a new theory of
olfactory perception. Drawing on research in neuroscience, physiology, and ethology …

Sniffing is a rhythmic motor process essential for the acquisition of olfactory information.
Recent behavioral experiments show that using a single sniff rats can accurately …

Sensory perception is not a simple feed-forward process, and higher brain areas can
actively modulate information processing in" lower" areas. We used optogenetic methods to …
